this is because the present general led lighting drive power of the working life depends on the smooth ac-dc circuit must beused when the electrolytic capacitors. we know that the working life of led up to 40,000 hours, [link widoczny dla zalogowanych] while the electrolytic capacitor life span of only a few thousand hours of the life of the system components from power supply electrolytic capacitors used in life to decide, if you do not mind electrolytic capacitors removed, then led lighting.
output capacitor uses two about 5μf the mlcc. ac100v and 200vinput voltage to support two. it is understood that, under normal circumstances,[link widoczny dla zalogowanych] the capacity mlcc can not fully absorb the pulsating current, but by improving the control of d-side will not feel the lighting flicker. non-insulated main circuit buck, do not set pfc (power factor improvement) circuit.
